The 2025/26 figures are provisional. The Department for Education publishes revised ones later in the school year.
Progress 8 cannot be worked out for 2025/26, because the KS2 tests that give the starting point were cancelled in 2020 and 2021.
Results reflect the pupils a school admits as well as its teaching, and a year's results can move a lot in a small school.
